Water: Coastal indigo thrives in areas with regular rainfall and prefers consistent moisture, ideally requiring weekly watering. This plant tolerates moderate drought but flourishes when soil is evenly moist. Typically grown outdoors, it benefits from full sun exposure and mulching to retain moisture and reduce watering frequency.

Fertilize: Coastal indigo should be fertilized with a balanced, slow-release fertilizer in spring and summer, applying quarterly. During active growth, extra nutrients are beneficial, while fall feeding should be reduced and stopped in winter. Avoid over-fertilization to protect roots; distribute evenly away from stems and leaves.

Pruning: Coastal indigo benefits from early to late spring pruning, which includes trimming dead branches and pinching tips to encourage bushiness and blooming. Regular thinning improves air circulation, while clean, sharp tools promote healing and prevent disease, ensuring a vigorous, healthy plant appearance.

Propagation: Coastal indigo propagates best through fresh seeds in well-draining, organic-rich soil. Lightly covering seeds enhances soil contact for germination. Maintain consistent moisture without overwatering, and ensure ample sunlight post-germination for optimal growth.
